It sure does look like the Surcouf but not exactly.
This is a strange duck. The enclosure looks different from the Surcouf but that could be due to the camera angle. What bothers me is the difference in the deck plating. However the cutouts for the diving plans seems to match that of the Surcouf.
There also seems to be differences in the conning tower and I would have expected to see the painted markings a bit clearer.
One the other hand, if it aint the Surcouf, what is it? Not British, Russian, Dutch, Japanese, US, or Italian. At least not that I can research.
I even took a closer look to see if this was a faked picture. But it looks real.
I would be willing to put the differences down to poor camera angle and call this the Surcouf..... nor not.
